similar to: lda discriminant functions

Hi, I'm writing for a little help. I have a dataframe with same NA value and I'd like to obtain the means of the value of a coloumn grouped by the levels of a factor coloumn of the datframe. I'm using the function "tapply" but I see that if only a NA value is present the result is NA. There is an option to have the correct result or I must use an other function? Thanks of

Hi, I'd like plot a bar graphic of a array. I'd like to have the values of the single columns as juxtaposed bars (like in "barplot" with beside=TRUE) and I'd like to have the values of the single columns expressed like percentage of the sum of the coloumn. In this way all the bars are composed by the sum of the percentage of the values of a coloumn (with different colors)

Hello, I'm tring to make a linear discriminant analysis eith lda (MASS). In the value of the resulting object is there information about the value of the centroids of the discriminated group for the discriminant functions? Thank you in advance for your help!

Hi all, I have a simple question: I have a data.frame like this: id x y 1 50 1647685 4815259 2 50 1647546 4815196 3 50 1647454 4815294 4 50 1647405 4815347 5 50 1647292 4815552 6 50 1647737 4815410 7 74 1647555 4815201 8 74 1647464 4815023 9 74 1646970 4815129 10 74 1646895 4815264 11 74 1646762 4815513 and I'd like to trasform it with the "convert.to.shapefile"

Hi all, I have a little problem selecting some rows from a data.frame. I'd like to select the rows where a determinated column take a partivolar value. For example: tab id x y 1 24-2005 1621814 4834991 2 24-2005 1621856 4834907 3 24-2005 1621763 4834956 4 25-2006 1622330 4835189 5 25-2006 1622533 4834834 6 25-2006 1622535 4834909 7 25-2006 1622543

Hi all, I have a simple question: I have a character vector like this [1] "10_1" "1_1" "11_1" "2_1" "3_1" "4_1" "5_1" "6_1" "7_1" "8_1" [11] "9_1" "1_3" "2_3" "3_3" "4_3" "1_4" "2_4" "3_4"

Is that a method where a program that I write today would still run without changes in 10 years?

There is a fairly straightforward way to load older versions of packages, and that is to use the 'groundhog' package. As the first sentence of https://groundhogr.com/ puts it: Make your R scripts reproducible by replacing library(pkg) with groundhog.library(pkg, date). pkg can be a vector of package names or a single name.

Dear list, there seems to be a problem with the standard location of R?s 64-bit libs at least under openSUSE. I had two user questions regarding the compilation of rpy2 for 64-bit systems. Personally I don`t know rpy2 but maybe someone on this list can decide if the mistake lies on R`s side or on rpy2?s side or in between. R-devel is installed in these cases, I asked. Latest R-base or

Dear all, I have uploaded to CRAN the version 1.8 of the package 'adehabitat'. Significant changes are listed below: * getverticeshr now relies on the function contourLines(), and returns smoother estimates of the kernel home range (see the help page). * the new function kernelkc (and related functions) now allows the estimation of the utilization distribution in space and time of

I've been using * at home for a while now and I'm quite happy with how it works.

Hello R developers, I know it is still a bit early to talk about Summer of Code, but I wish to know what are, approximately, plans for this year. Last year I applied as a student under OSGeo with a QGIS-R project and had a very positive experience [0], therefore I plan to participate again. I found an interesting hint [1], about implementing fractal analysis in R, and a would-be mentor has

Dear all, I'm using the package adehabitat in R to import several .asc files (=matrix), and also create a kasc object (=dataframe) with all of them. The main idea is to use this kasc object to map the predicted values of climate-matching model for an overall area. However, I don't know how to proceed: Do I have to project the model (already stored in R) onto the kasc object directly, or

Hello, I wuold like to propose my modifications of the original cor.test to you : I tried to calcolate the correct p-value for Spearman and Kendall's test with ties. Let me know what you think.
